1、2012届高三英语二轮复习精品学案（湖北专用）：第4模块 完成句子 专题6 情态动词与虚拟语气专题导读情态动词与虚拟语气是高中语法学习的难点和重点。高考英语完成句子对情态动词的考查主要涉及常见情态动词的基本用法，特别侧重于情态动词表推测的用法和特殊结构中情态动词的应用。高考完成句子对虚拟语气的考查重点在于根据句子的语境灵活多样地运用虚拟语气，宾语从句中虚拟语气的应用，交际用语中为表委婉而使用的虚拟语气，含蓄条件句中的虚拟语气，以及特殊句型中的虚拟语气等。学好虚拟语气，除了掌握基本的结构外，还要注意句子所表达的意义是与现在、过去，还是将来事实相反，看清时间状语，另外还要注意在其他结构中虚拟语气的
2、运用。五年高考已考测试点：情态动词与完成式；宾语从句、同位语从句、条件句中的虚拟语气；情态动词的推测功能；should/can等情态动词的基本用法。2012年复习备考考点聚焦： 考点(1)情态动词与完成式“情态动词have过去分词 ”结构是情态动词专项考查的难点和重点，记住以下最常考查的结构：must have done 过去一定做了某事cant/couldnt have done 过去不可能做了某事may/might have done 过去可能做了某事neednt have done本来没有必要做而实际做了某事could have done本来能够做而实际没有做某事should/ought
3、 to have done本来应该做而实际没有做某事shouldnt/oughtnt to have done本来不该做而实际做了某事考点(2)情态动词的推测功能can，could，may，might，must 皆可表示推测，使用时要注意以下几点：注意语气。语气较强用must, cannot，couldnt；语气较弱may，might或can，could；注意句式。在肯定句中，一般用may，might，must；在否定句、疑问句中常用can，could；注意时态。表示对现在或将来的情况的推测，此时通常用“情态动词 动词原形”结构；表示对现在或将来正在进行的情况进行推测，通常用“情态动词进行式”
4、结构；表示对过去情况的推测，通常用“情态动词完成式”结构。考点(3)can的一些特殊搭配 canttoo/overcantadj./adv. enough 再也不过分cant help/choose but do 不得不做cant help (to) do不能帮忙做cant help doing情不自禁做cant/couldnt agree more 十分赞成it cant/couldnt be better 十分好，非常好might as well还是的好；不妨考点(4)虚拟语气的基本用法 与现在事实相反的虚拟语气，基本结构为：主语动词的一般过去时(be动词用were)其他成分if主语sho
5、uld/would/could动词原形其他成分。 与过去事实相反的虚拟语气，基本结构为：主语动词的过去完成时其他成分if主语should/would/couldhave done其他成分。 与将来事实相反的虚拟语气，基本结构为：主语动词的一般过去时/should do/were to do其他成分if主语should/would/could动词原形其他成分。 考点(5)含蓄虚拟条件句这样的虚拟句不含有if从句，而是以but for/without/or/otherwise等引导的句子代替if从句，主句的谓语动词的形式与前面虚拟语气的基本用法相同。 考点(6)主从句时间不一致的虚拟条件句 在有些
6、虚拟条件句中，主从句时间不一致，应根据不同情况区别对待。 考点(7)名词性从句中的虚拟语气 在含有表示坚持、建议、命令、要求等含义的名词性从句和在it作形式宾语或形式主语的复合句中，宾语补足语是necessary/strange/essential/natural/a pity/a shame等表示“惊奇、惋惜或者理应如此”等含义时，从句中的谓语动词需用“should动词原形”，其中should可以省略。 考点(8)wish/if only/would rather从句中的虚拟语气wish，would rather引导的宾语从句及if only所引导的从句，须用虚拟语气，即从句用一般过去时(b
7、e用were)表示与现在或将来的事实不符；从句用过去完成时，表示与过去事实不符。真题典例12011湖北卷 If _(我没有喝) alcohol last night, I could have driven my car home. ( drink )in helping transport and pull up the stones.(hand)1I hadnt drunk考查if引导的虚拟语气。根据主句I could have driven my car home，可以判断该处是对过去时间的虚拟，故分句部分要用过去完成时，由此可知答案为I hadnt drunk。22010湖北卷 Mr.
8、 Johnson insisted that the problem worthy of attention _ (讨论) at the meeting. (discuss)2(should) be discussed考查虚拟语气。insist引导的宾语从句要用虚拟，从句结构是 “(should)动词原形”；主语 problem与“讨论”之间是被动关系，故答案为(should) be discussed。32010湖北卷 Its said that they have swum to the island from the continent, but they _(不可能做到)because

11、。7He believes that children_(应允许学习)at their own pace. (allow)7should/ought to be/must allowed to learn/study考查情态动词的用法和非谓语动词。根据提示词首先选定情态动词should/ought to/must；“允许”要表达为allow sb to sth，此处是被动语态，由此可知答案为should/ought to/must be allowed to learn/study。8It is possible that the King of Stonehenge was linked t
12、o the stones: he_(可能参与) in planning the monument, or 8may/might/could have had a hand考查“情态动词完成式”。表示“可能性”应用may/might；由于是对过去情况的推测，动词应该使用完成式；表示“参与”应用动词短语have a hand in，由此可知答案为may/might/could have had a hand。新题预测考试动向预测(110小题)：1When Edison died, it was suggested that the American people _ all power for s
